  2. Agenda – Core Project Updates • NMMS • EMS • MMS • CRR • COMS Program Update

  3. NMMS Update • Continuing NMMS 4 FAT – 8 Outstanding Sev 1/Sev 2 defects • Provided V1.20 CIM XML files with test data to AREVA and ABB for consumption • Coded & implemented Data Validation Set 0 (mandatory attributes, mandatory associations) • Coding incremental Data Validation Set 2 (RARF, CRR, & Planning) • Coding incremental Data Validation Set 3 (EMS & MMS) Program Update

  4. EMS Update – CIM • Completed three weeks of data correction / testing at ERCOT • Number of data issues have been reduced from over 20,000 (week of Aug. 8) to 54 (week of Aug. 29) • New NMMS model provided on Aug. 29 – verifying 3 issues from the build, 2 issues re-opened, and new issues opened. • Next NMMS model drop planned for Sep. 5 • ERCOT SMEs continue to test with AREVA to identify/resolve issues • Running validation and cross validation routines – all run successfully except Generation and ICCP • Running individual applications • SCADA – running successfully multiple days with a few minor data errors, feeding data to State Estimator • ICCP – running validation and reviewing the save case • Generation – limited success, but addressing 50 data errors and a potential code issue • Dynamic Rating – validated the save case is correct • Network Applications • Study Load flow ran successfully • State Estimator is running successfully over multiple days; Contingency Analysis has limited success due to configuration data and code issue Program Update

  5. EMS Update – 2 • Software Releases • EMS 5.1.5 for Outage Evaluation (OE), Voltage Support, etc. has finished execution of planned FAT test scripts. Release is held up by several OE-specific defects – new target Sep. 19 FAT Sign off • EMS 5.1.7 Habitat 5.1.7 released to ERCOT several months ago, awaiting an opportunity to place in ERCOT FAT • EMS 5.1.8 EMS CIM Importer – Application testing in progress to validate the database build, restart Pre-FAT at ERCOT in mid-September • State Estimator and Telemetry reports / extracts (EDW 1) • Completed User Acceptance Testing and are now approved by ERCOT for posting to the EDS environment • State Estimator Reports / Extracts: • SE Convergence Rate Report • MW Residuals SE Vs Telemetry for Congested Transmission Element Report • Buses Not Meeting Telemetry Standards Report • MW Residuals SE Vs Telemetry for Major Transmission Elements Report • State Estimator Statistics Extract • Telemetry Reports: • Critical Data Availability Statistics Report • Monthly Market Participant Real Time Availability Statistics Report • Quarterly Point Availability Statistics Report • ICCP Link Availability Program Update

  6. Project Update – MMS • MMS Processes & Procedures (DAM, RUC, Adjustment Period and Real-time) • MMS and MOS team members are leading the development of these documents • Process reviews are scheduled with TPTF for August, September and October meetings • Software Releases • MMS 4 • Complete patch 2 FAT testing on August 26 • Started patch 3 FAT testing on August 26 • Patch 4 delivered to ERCOT on August 27 (originally targeted for August 31) • Will use same CIM XML test data set as patch 2 and 3 • Focused mainly on outstanding defects • MMS4 patch 5 is targeted for delivery on September 30 • Targeted to include Settlements and Billing defects, interface updates, and additional workflow development and testing with the most recent CIM schema and CIM XML test data set • CIM XML test data set version has been determined; will use v1.20 received from NMMS Program Update

  7. Project Update – MMS (cont.) • Software Releases (continued) • MMS5 is the last scheduled MMS software release • This release will be comprised of the following: • CIM XML import processing and testing end-to-end (defined in last bullet in this section) • Bug fixes identified to ABB during testing • Remaining work on NPRRs (e.g., NPRR113) • Remaining SIG paper work (e.g., rounding) • Remaining software implementation changes based on testing (e.g., performance improvements, startup cost eligibility, SASM constraint modeling) • Trigger start for MMS5 is a CIM schema and CIM XML data file validated and synchronized for consumption by EMS and MMS • Once the trigger is available, the following tasks will take place: • ABB final review and refactoring of all workflows using the complete CIM schema and CIM XML file • ABB completion of software updates for SIG papers, post baseline 2 NPRRs, performance and production readiness tasks, and outstanding defects • Pre-FAT in Santa Clara • Release preparation and delivery to ERCOT • Loading and smoke testing in MMS DEV and MMS FAT • Final regression testing of MMS system in FAT Program Update

  8. Project Update – CRR • Requirements for CRR Network Model One Line diagram approved by TPTF and TAC • Working with Nodal EMS project team to optimize development efforts for the CRR Network Model One Line diagram • Start of CRR4 FAT is planned for Sep. 19 – SMEs will test revised propagation of CRR Account Holder name changes within the CRR application Program Update

  9. Project Update – COMS • Settlements/Data Agg/CSI – Product Testing at ERCOT • Development • Settlements and Billing/Data Agg: Completed over 97% of nodal coding and functionally verified • Outstanding code (to date): • Data Agg: Reworking recent memory footprint release from Oracle into core code and regression testing • Internal/External Source Reports for Data Agg, Settlements, and CODIA • CSI: Completed over 85% of Lodestar Bill Determinants and verified • Testing • Continue to test core system with upstream system changes • Continue to optimize batch cycles • Major issues • Received a new memory footprint function from Product Memory mgmt issue. Currently reworking footprint functions into base code (added a final regression to schedule) • Need synchronous dataset from market systems (NMMS/EMS/MMS/CRR) running in an integrated environment before market level validation can begin (required for post Shadow Settlement Extracts) Program Update

  10. Project Update - COMS (cont.) • Registration and Disputes – Migrating to Integration Test • Registration 4 Release integration test scheduled for completion Dec. 5, 2008 • Registration 4 Release includes: • Siebel changes for nodal (defect fixes) • Siebel to Lodestar interface (upgrade/change from zonal) • Lodestar to Siebel Settlement Calendar Look Up • Major Issue • Integration rework needed for Zonal/Nodal cross impact created delay for Disputes API. Disputes API now targeted for January 2009 production delivery • Credit Monitoring and Management – FAT Testing • Build 3.1 (Vendor developed interfaces) in FAT 97% Complete • Build 3.2 (Settlement and Billing / Commercial System Integrated Releases) in development targeting October 2008 delivery to FAT • Major Issues/Risks • Finalizing detailed analysis and design of internal UI and reporting. Any changes from upstream systems, NPRRs or change controls have potential to impact schedule Program Update
